Definitions

  • the invention relates to a calibrating device for extruded plastics sections, comprising a number of calibrating units disposed, more particularly in a continuous cooling chamber under negative pressure and/or water, successively in the drawing-off direction of the section.
  • the individual calibrating units are aligned axially in relation to one another and mounted fixed on an understructure. It has been found that even when the greatest possible care is taken with the assembly of the individual calibrating units on the substructure it is impossible to achieve a 100% precise alignment of the up to 15 calibrating units. This means that the section to be guided through the calibrating units, which is in itself very rigid, is subjected to appreciable mechanical stressings. To prevent such stressings and the resulting increased shrinkage and/or surface faults, the dimensional tolerances of the plastics-contacting calibrating members and therefore of the plastics sections themselves have been increased. However, this step is not in harmony with the requirement to obtain sections having the maximum dimensional precision.
  • the section to be drawn off is not additionally stressed at the individual calibrating units on account of the alignment thereof not being 100% correct, because the calibrating units can be adjusted individually to the position of the section to be drawn off.
  • the acceptable stressing of the section at the individual calibrating units can be exhaustively used by the individual calibrating units to support the geometry of the section, since use can be made of calibrating units with close tolerances.
  • the result is sections of increased dimensional accuracy.
  • the close tolerances of the individual calibrating units lead to an improved cooling effect.
  • the improved cooling can be used to shorten the cooling path and/or to increase drawing-off speeds.
  • the use of the calibrating device according to the invention leads to sections of more accurate dimensions with smaller installations and/or with higher productivity, without increasing the shrinkage of the section.
  • the calibrating units can be adjustable on the guide in the drawing-off direction. This advantageously enables fluctuations in the external dimensions of the sections due to the material to be corrected by changing the distance between the individual calibrating units.
  • the guide can consist of rails on which the calibrating units are disposed after the fashion of carriages with lateral and vertical clearance and bear the adjustable stops, for the calibrating units.
  • FIG. 1 is a plan view of a guide having one calibrating unit drawn in solid lines and two calibrating units drawn in broken lines,
  • FIG. 2 shows the guide with the calibrating units in FIG. 1, sectioned along the line A--A in FIG. 1, and
  • FIG. 3 shows the guide with the calibrated units as in FIG. 1, sectioned along the line B--B in FIG. 1.
  • a calibrating device is disposed in a continuous cooling chamber (not shown) which is under negative pressure and/or water.
  • cooling fluid is sprayed on to the extruded section on all sides, so that it becomes very rigid by the completion of its travel.
  • the calibrating units passed during said travel ensure that the section leaves the cooling chamber with the minimum dimensional tolerances.
  • the calibrating device shown in the drawings has two parallel guide rails 1, 2 retained by crossheads 3, 4 disposed at the ends. Mounted spaced out in the drawing-off direction on the guide rails 1, 2 are three calibrating units 5, 6, 7. The calibrating units 5 to 7 are identically constructed, so that the following description can be limited to the calibrating unit 5 illustrated more particularly.
  • the individual calibrating units 5 to 7 can be equipped with separate vacuum and tempering connections.
  • the calibrating unit 5 has an opening 8 through which the section to be extruded can pass. On the underside it has two gate-arch-like recesses 9, 10 in which the guide rails 1, 2 are disposed.
  • the guide rails 1, 2 are retained in the recesses 9, 10 by means of pivotable claws 11, 12 borne by the calibrating unit 5.
  • the guide rails 1, 2 are at a distance from the recesses 9, 10 and the claws 11, 12 on all sides, so that the calibrating unit 5 can move in all directions of the plane normal in relation to the drawing-off direction.
  • the calibrating unit 5 is therefore mounted floatably on the guide rails 1, 2.
  • the position of the calibrating unit 5 in the drawing-off direction is determined by a stop 13 which can be clamped steplessly on the rails 2.
  • the individual calibrating units 5 to 7 are simply placed on the guide rails 1 and secured against lifting-off by the claws 11, 12. Due to the clearance on all sides at the guide rails 1, 2, the individual calibrating units 5 to 7 can be laterally adjusted on the section passing through, so that the section experiences no lateral displacing force at the individual calibrating units 5 to 7. The stressing of the section at the individual calibrating units 5 to 7 is therefore reduced in comparison with the stressing in a known calibrating device.
